Meanwhile, the movement of the electric drive unit 41 in the automatic exhaust drive device is converted into the horizontal movement of the exhaust push rod 42 through the connecting assembly, and then the exhaust push rod 42 horizontally moves to push the exhaust valve 3 to move, so that the movement stability of the exhaust push rod 42 is improved, the reliability of the exhaust action is improved, and the whole stroke of the automatic exhaust drive device can be reduced, thereby reducing the whole occupied space of the automatic exhaust drive device and being beneficial to reducing the whole volume of the cooking utensil 100.

According to some embodiments of the present invention, the coupling assembly includes an automatic venting rod 431 and a venting lever 432, the automatic venting rod 431 and the venting lever 432 are rotatably provided in the lid 2, respectively, and the second magnetic material piece 52 is provided on the automatic venting rod 431. Specifically, referring to fig. 2 and 3, a second magnetic material 52 may be provided at a lower end of the automatic exhaust rod 431. The electric driving unit 41 may be located below the automatic air release lever 431, and when the electric driving unit 41 moves below the automatic air release lever 431, a magnetic force may be generated between the first magnetic material 51 on the driving lever 411 of the electric driving unit 41 and the second magnetic material 52 on the automatic air release lever 431.
